Abstract: The natural emergence ratio of 6 species common flies in north was studied; 1. Musca domestica L. , 2. Muscina stabulans (Fall.), 3. Lucilia sericata(Mg.), 4. Chrysomya megacephala(Fab.), 5. Aldrichina grahami(Aldrich.), 6. Calliphora vicina R.-D. . Two of them, Musca domestica and Lucilia sericata, are the most important species in the north of China. The peak of emergence is June and August as M. domestica and May and June as L. sericata.

摘要： 作者于1987年对我国北方常见的6种蝇类的自然羽化率进行了研究,发现家蝇的全年自然羽化率高峰在6、8两个月,厩腐蝇为6月份,丝光绿蝇为5、6两个月,大头金蝇为6月份,巨尾阿丽蝇和红头丽蝇为5、8两个月;蝇类自然羽化率高峰总是出现在成蝇季节消长高峰之前。作者认为,以自然羽化率为指标,可推测成蝇种群密度高峰出现的时间,从而制定出相应的防蝇、灭蝇措施,亦有助于预防肠道疾病。
